How to survive in the blogging world:
Thou shall cite thy references. You’ll look knowledgeable, honest, and trustworthy.
Thou shall own up to thy mistakes. Instead of being defensive and denying it, just admit your blunder and move on.
Thou shall not invoke personal attacks. Rule of thumb: Argue with the post, not the poster.
Thou shall stick to the subject at hand. If you’ve got something wildly off topic to say, start a new thread or keep it to yourself until it becomes relevant.
Thou shall punctuate and capitalize. Writing several paragraphs as one gigantic, all-lowercase, run-on sentence is a definite no-no. Punctuation is your friend, so use it.
